When heat treating stainless steel, is it necessary to freeze it to very low temperatures (-100F)? What advantages does this give and what happens if you don't do it?

Can anyone point me to an article on the subject? I've read a few on heat-treating, but they were all concerned with the carbon steels, not stainless. Thanks, guys.
 
Cryogenically treating high carbon and alloy carbon steels transforms retained austenite to untempered martensite. It is very beneficial in prolonging the life of the tool.

When you are reading anything on knife steels keep in mind that Stainless Knife steel is a carbon steel with Chromium added for stain resistance. The mechanisms for heat treating are essentially the same for stainless and non stainless steels.
